Referring to fig. 5, the unlocking assembly 7 includes an unlocking lever 71 slidably coupled to the installation housing 2 and having both ends respectively located at both inner and outer sides of the installation housing 2, a pressing cap 72 fixedly coupled to one end of the unlocking lever 71 located at the outside of the installation housing 2, a return spring 73 sleeved on the unlocking lever 71 and located between the pressing cap 72 and the outer wall of the installation housing 2, and a stopper 74 fixedly coupled to the unlocking lever 71, the stopper 74 being located inside the installation housing 2. The length direction of the unlocking rod 71 is perpendicular to the length direction of the mounting shell 2, the section of the pressing cap 72 is U-shaped, and the unlocking rod 71 is fixedly connected to the bottom of the U-shaped groove of the pressing cap 72. Normally, under the elastic force of the return spring 73, the unlocking rod 71 is given a sliding force to the outside of the installation shell 2 by the pressing cap 72 until the limiting ring 74 abuts against the inner wall of the installation shell 2, so that the sliding limit position of the unlocking rod 71 is limited, and at this time, a gap is reserved between the unlocking rod 71 and the clamping plate 61, and the unlocking rod and the clamping plate are not contacted with each other.

When the piston rod 4 needs to be removed from the sliding block 51 after the balloon 12 is inflated, a worker directly presses the pressing cap 72 outside, and at this time, the pressing cap 72 drives the unlocking rod 71 to slide towards the inside of the installation shell 2 and presses the reset spring 73 until one end of the unlocking rod 71, which is positioned inside the installation shell 2, abuts against the clamping plate 61, and along with the continuous sliding of the unlocking rod 71, the unlocking rod 71 also drives the clamping plate 61 to rotate so as to press the abutting spring 642, and at this time, the clamping plate 61 also drives the two hooks 62 to be away from each other, so that the opening of the placement space 63 is enlarged, and the worker directly takes out the fixing plate 43 from the placement space 63.

Referring to fig. 5, a protection barrel 75 is fixedly connected to the outer surface of the installation shell 2, the protection barrel 75 is sleeved on the unlocking rod 71, and the pressing cap 72 is positioned inside the protection barrel 75, so that the protection barrel 75 can seal the part between the pressing cap 72 and the installation shell 2, and the influence of external impurities on the service life of the return spring 73 caused by the fact that the external impurities reach the return spring 73 from the position between the pressing cap 72 and the installation shell 2 is avoided.

Meanwhile, in order to avoid the influence of the part of the unlocking rod 71 penetrating through the installation shell 2 on the overall strength of the installation shell 2, so that the installation shell 2 is damaged due to stress, a reinforcing cylinder 76 is fixedly connected to the outer wall of the installation shell 2, and the reinforcing cylinder 76 is sleeved on the unlocking rod 71 so as to increase the support of the installation shell 2 and protect the installation shell 2. And a sliding space into which the pressing cap 72 is fitted is formed between the outer wall of the reinforcing cylinder 76 and the inner wall of the shielding cylinder 75, and when the pressing cap 72 is pressed down, the pressing cap 72 slides in the sliding space.
